java.lang.Object weblogic.wtc.jatmi.StandardTypes weblogic.wtc.jatmi.MBStringTypes weblogic.wtc.jatmi.TypedFML32
This implements TypedFML32 in JAVA as a TypedBuffer. Fieldids are generated with the tool mkfldclass32, and then put into the buffer with the appropriate TypedFML32 methods. Note that in this implementation Fieldids must be combined into a field key, which is a combination of the Fldid32 and the occurance number. Any number of field tables can be loaded into any TypedFML32 object in order to do FldId to String conversions and String to FldId conversions.

Constructor Summary | |
TypedFML32()
Default constructor. |
|
TypedFML32(FldTbl table)
Constructor which provides a single FldTbl object for mapping FldIds to Strings and Strings to FldIds Note that it is not necesary to provide FldTbls unless String/FldId mappings are required. |

TypedFML32(FldTbl[] tables)
Constructor which provides a list FldTbl objects for mapping FldIds to Strings and Strings to FldIds. |
|
TypedFML32(TypedFML32 copyFrom)
This constructor copies the fields from the input FML32 buffer. |
